Weird issue with O2
 

Hi all,

trying to work out if its a phone issue or a sim card issue with o2. my mum currently can't hear anyone when she makes calls and they can't hear her. after the call ends it comes up with "call failed".

I've tried switching it on/off and resetting too. but no joy. when i reset it works for like 10 seconds and then stops working again. someone on reddit said theyre encountering the same issue. its an iphone 12.

any suggestions? off to the o2 shop tomorrow otherwise (i.e. today!)

Try the sim in a different phone if you can. That will rule out the device if it still happens.

I've personally not had any issues with O2 in Glasgow.
